[Identity] Disable interactive prompts in `AzureDeveloperCliCredential` token commands

[pvaneck]

If a user has the AZD_DEBUG environment set, the azd auth token subprocess will hang and eventually timeout because it's waiting for user input:

$ azd auth token --output json --scope https://search.azure.com/.default
? Debugger Ready? (pid: 259503) (Y/n)

To recreate, just set AZD_DEBUG=1 in your environment and get a token using AzureDeveloperCliCredential.

To avoid this scenario, we should pass in --no-prompt in our token command when calling azd.
